In order to get the proper size for the challenges, this is what I do:
Load the photo into Photoshop and save as a .tif with a resolution of 200. Then I size it to 4x6" and save it. Then I do the editing I want to do, save it again. This copy I keep in a separate file -- I make notecards, and I normally use this size for prints, and the high resolution is necessary for that. (If I upload it to order prints, I will make a .jpg of the file.)
Then I size the longest edge as 640 and save it as a .jpg and look at the total number of bytes of the photo in CompuPic.
The photo is always too big at this point. I will lower the Image Quality under "save as" to 8, but no lower. Then I will lower the resolution of the photo as far as I need to in order to get the 150k. I usually end up with a resolution of at least 100 doing this and I can get within the boundaries of the rules.
I heard once that a resolution of 72 is all you need for a photo to view nicely on a monitor -- at least I think I heard that once.
Am I doing too much work here after I make my 4x6 .tif? Should I simply change the resolution to 72, make the longest edge 640, set the Image Quality to high and leave it at that?
Thanks.

You MAY be making it harder...here's my steps starting from the TIFF:
1-ImageSize with the "resample" box Unchecked - set resolution to 72
2-ImageSize with Resample Checked - set longest side to 640; the "inches" value will now reflect how large the image appears on monitor
3-SaveACopy in JPEG -- I save with progressively lower quality settings until I get under 150k. I'm using Photoshop 5. For PS 7 you can do the same with SaveForWeb and use the slider.
If you won't go below the 80% quality setting and the photo is still too big, you'll have to make it smaller than 640 to start with, like you seem to be doing now. You can also try cropping two sides and changing the aspect ratio to get it a little smaller -- you're not restricted to any standard sizes for your entries. If the image is right around 150-155k, and you're willing to add a border, you can sometimes reduce the file size by adding a moderately sized (4-10 pixel) solid stroke. |

Here is what I do:
Make my crop on the original.
Resize that to make the longest size 640.
Save making the quality as near as I can to 150kb.
It seems very simple after all the stuff you do.
